You're not wrong that economics motivate the choice of where to hire for a customer support function. Customer service is a cost center, so naturally companies will choose to hire where labor is cheap
but the job can still be done. If it's not being done well, that's a problem to point out. But that's not what happened in this conversation.
To reiterate, here is how this thread went, in context:
>> I think you are underestimating the value of providing support to commercial users.
> You mean, the valuable support they are increasingly shifting to Colombia, Philippines and India?
The bottom reply added no value to the conversation; it made no substantive claim. Since it lacked any substance, the reply merely insinuated that people from these countries cannot provide support at a level that people from other countries (such as the USA) can, and without any explanation as to why. This is the modus operandi of racists who want to choose not to be overt - leaving it to the reader to implicitly understand the unstated. Some call it a "dog whistle."
Had the speaker said "well, they're moving these functions to Colombia, Philippines and India, which are providing worse service because of <some non racist reason>," the conversation would have gone rather differently.
> You are either a racist, unintelligent, or else ignorant. You do not write as though you're unintelligent. I do not personally assume that people are racist because I disagree with them (though your writing makes me challenge that). I can therefore only conclude you're ignorant of what real people do at real jobs.
I'm not going to dignify this with a response. Take this garbage to Twitter where it belongs.
